《Tilz Tilz MacWilliams 3》 The Tilz MacWilliams model is a very popular model, used by many players from beginners to advanced players. This is the model of Mr. Fergus McWilliam, former horn player of the Berlin Philharmonic. Inner diameter 17.50 Bore 4.00mm Shallow cup Purchased at a musical instrument store in Tokyo a few years ago. There are some scratches, but there are no dents and it can be used without any problems. I mainly used it with Alexander horns. I liked the enveloping rich tone and the ease of controlling from low to high notes, so I used it. I will wrap it in bubble wrap and ship it by post. * Due to the nature of the mouthpiece, there may be fine scratches due to contact during instrument attachment, care, cleaning, and wiping.
